San Francisco supervisors balk at 362-page, AI-assisted city code rewrite

The San Francisco Board of Supervisors postponed voting on a 362-page ordinance that would make over a hundred changes to the city code, after several supervisors and the board clerk raised concerns that the proposal was too broad and unclear. The ordinance, a product of AI research with Stanford University, aims to remove redundant and obsolete reporting requirements.

A new AIS-heading technique to track grain smuggling

This article describes a new method using Automatic Identification System (AIS) heading data to track grain smuggling from occupied Ukraine to Libya. In February 2026, the bulk carrier Grumant loaded grain at the occupied port of Feodosia in Crimea and after a two-month journey arrived in Benghazi, Libya. Due to GNSS interference in the Black Sea, AIS position data is unreliable, but heading data from the ship's compass is unaffected and can be used to confirm location. By analyzing Grumant's heading data alongside satellite imagery, researchers confirmed its presence at Feodosia. This technique provides a new tool for tracking illicit shipping.

Fable is coming back: Federal government lifts export controls on Anthropic AI model

The U.S. Commerce Department has lifted export controls on Anthropic's Fable 5 and Mythos 5 AI models, allowing Fable to return to users. Anthropic agreed to proactively detect and address security risks and work with the U.S. government on protocols. The controls were imposed over two weeks ago due to a 'jailbreak' concern, causing industry unease.

Multi-token Residual Prediction

Multi-token Residual Prediction (MRP) is a lightweight module for diffusion language models that predicts the residual between adjacent denoising steps rather than the full distribution. This enables both lossless speedup in static regimes (up to 1.56×) and quality recovery in dynamic regimes (up to +16 accuracy points) without trade-offs.

Announcing our $800M Series C to accelerate the shift to open-source AI

Together AI raised $800M in Series C funding to accelerate the shift to open-source AI. The company argues that closed models' economics don't scale, and open models combined with full-stack optimization can achieve 6-20x cost reductions. Together AI has launched innovations like FlashAttention-4 and Together Megakernel, becoming one of the world's largest AI token producers.

Ahmad Osman on why local AI is catching up

After two packed AIEWF workshops, Ahmad Osman makes the case that local AI is catching up fast — from laptops and phones to enterprise-grade infrastructure. Open-source models are narrowing the gap with proprietary frontier models, and the local AI ecosystem is expanding beyond models to include complete tooling and infrastructure layers.

Claude Sonnet 5: strong agentic performance at a higher cost per task

Claude Sonnet 5 scores 53 on the Artificial Analysis Intelligence Index, matching GPT-5.5 with high reasoning but behind Opus 4.7 and 4.8. It costs $2.29 per task, ~15% more than Opus 4.8, driven by increased token usage. Sonnet 5 matches or outperforms Opus 4.8 on agentic knowledge work tasks but lags on reasoning-heavy benchmarks. It retains a 1M token context window and adds an 'xhigh' effort setting.

AI in higher ed: just like the shock of the Internet and the web?

This article examines AI's impact on higher education, comparing it to previous technological shocks such as the Internet, big data, and MOOCs. The author argues that while these earlier shocks had limited effects on core educational practices, AI's impact is more profound, broad, systemic, and rapid, potentially transforming the very nature of learning and teaching.

Never Trust a Number

The author argues that most numbers we encounter in news, reports, and daily work are wrong or misleading. Citing examples from the New York Times misstating global COVID cases by a factor of 1,000, confusing wheat production with exports, and workplace errors involving cost overruns and unit mix-ups, the essay builds a case for default skepticism. The underlying message: numbers are powerful but dangerous shortcuts; real understanding requires effort and multiangle verification.
